The Type DT5 represents an electric multiple unit (EMU) train model utilized by Hamburger Hochbahn AG within the Hamburg U-Bahn system. Notably, it is the inaugural rolling stock on the Hamburg U-Bahn to incorporate both air conditioning and inter-car gangways.
Formation
A DT5 trainset consists of three cars permanently linked together, featuring gangways that allow passengers to move freely between them. It is possible to couple up to three of these trainsets in operation.
Interior
Inside, the train is equipped with red fabric seats, designated areas for wheelchairs and strollers, next-stop information displays, and surveillance cameras. Passenger comfort is further improved by the inclusion of climate control through air conditioning.
Technical specifications
The DT5 employs an articulated configuration where each of the two end cars rests on a single bogie, while the middle car rides on two bogies. The car bodies are made from stainless steel and powered by three-phase electric motors. To achieve weight reduction, aluminium brake discs are used, which emit a characteristic squealing sound when braking.
History
In 2005, a tender process was launched across the European Union for the procurement of the DT5 trains. Participants included Siemens, Stadler, Rotem, and a joint bid from Alstom and Bombardier. The contract was awarded in December 2006 to the Alstom-Bombardier consortium at a specified cost. The initial unit arrived at the Barmbek depot on December 1, 2011. Additional orders placed in 2016, 2018, and 2019 expanded the fleet size to a total of 163 units.
